Powder distributors



Aug. 13, 1963 C. W- ROBINETTE POWDER DISTRIBUTORS Filed July 7, 1961 INVENTOR a. 14 FOE/M6772?) ATTORNEYS of Missouri Filed July 7, 1961, Ser. No. 122,530 3 Claims. (Cl. 43-146) This invention relates to improvements in powder distributors adapted for use particularly with insecticldes, fungicides, rodenticides, and other materials capable of being handled and distributed in such manner.

Distributors have been provided heretofore for this purpose, but due to the construction thereof, these have not had all of the advantages of which such devices are capable, and it has been desirable to make improvements therein.

One object of this invention is to improve the construction and handling of such distributors for various powdered materials.

Another object of the invention is to provide for a stopper closure in the distributor, with provisions for effective sealing of the stopper when inserted therein, with a tight joint therebetween.

:Still another object of the invention is to provide a hook or handle on the distributor to facilitate carrying and handling thereof without adding appreciably to the complexity or cost of the structure.

These objects may be accomplished, according to one embodiment of the invention, which is illustrated in the accompanying drawings, in which:

FIG. 1 is a vertical sectional view through the distributor on the line 11 in FIGURE 2;

FIG. 2 is a horizontal section therethrough, on the. line 2-2 in FIG. 1; and

FIG. 3 is a side elevation of the distributor on a smaller scale.

The distributor illustrated as an embodiment of this invention comprises top and bottom members 1 and 2, connected together by a collapsible side wall section 3. These parts cooperate to form a container for the mate rial to be distributed and discharged therefrom.

The top element 1 is formed with an end wall section 4, having a surrounding inturned sleeve 5 spun or other Wise formed on the end wall 4 and extending downwardly therefrom. The end wall 4 is provided with a filling opening 6 therein, having a downturned flange 7 around the filling opening to provide a smooth edge thereon. The stopper 8 is adapted to be inserted in the filling opening 6. The inturned flange 7, formed around the filling opening 6, provides a tight joint between the stopper 8 and the top element 1. The stopper 8 may be formed'of any suitable material and preferably is of cork, rubber or other cushion material suitable for the purpose.

The bottom member 2 is provided with a bottom closure wall 9 having an upturned sleeve section 10 formed thereon, as by spinning or otherwise, so as to provide a bottom closure and cup-like portion for the dispenser.

The side wall section 3 preferably is collapsible, to effect a bellows action for the dispenser. In this embodiment, the section 3 is formed as a rubber or elastic sleeve telescoped at its opposite ends over the sleeve sections 5 and 11 formed on the top and bottom members 1 and 2. The overlapped edges of these parts are preferably secured tightly together as by wire or other form of clamps, indicated generally at 11. Each of the sleeve sections 5 and 10 is formed preferably with an annular circumferential indentation 12 therein, so as to permit the clamps 11 to force portions of the elastic sleeve 3 into the circumferential indentations and thereby effect a tight connection between the surrounding sleeve 3 and the end members 1 and 2.

3,193,362 Patented Aug. 13, 1963 A coiled spring 13 extends axially between the end walls 4 and 9 to assist the elastic sleeve 3 to return these parts to expanded position when collapsed.

The bottom member 2 is provided with an opening 14. in the sleeve section 10 thereof through which a tubular discharge spout 15 extends from a point diametrically across the bottom member 2, as will be apparent from FIGS. '1 and 2. The discharge spout is formed somewhat conical, to facilitate the discharge of the material. The opposite sides of the spout 15 are provided with openings 16 in the section thereof within the dispenser forming inlets for the powdered material. The end of the tubular spout within the dispenser is closed by being pinched together, as indicated at 17, and preferably abuts directly against the adjacent sleeve section 10 on the bottom member 2. This spout may be attached to the bottom member at this point by being secured in any suitable manner, as, for example, by soldering, welding, or the like.

A hook or handle 13 is provided on a side of the distributor adjacent the bottom thereof. This hook or handle is made of wire which protrudes through the sleeve section 10 on the bottom member 2, with its inner end being curved around the inside surface of the sleeve section 10 through more than as indicated at 19. The inner end section 19 should be secured effectively to the bottom member 2 as by soldering, welding, or the like, and it may overlap the pinched end 17 so as to utilize one point of fastening for both elements, as well as aid in re taining the spout in place.

The outer end of the wire handle 18 extends radially outward from the sleeve section 10 on the bottom member 2 to a desired extent, as for example, /2 inch, and then is turned upward, as indicated at .20, with the extreme end thereof bent back upon itself at 21. This leaves an opening between the container wall 3 and the hook portion 20 of about /2 inch, to facilitate handling and carrying of the distributor, and it also permits the distributor to be turned upside down and to be hooked over a suitable support in such inverted position when stored or when not in use.

In using the distributor, the powdered matenial is introduced into the container through the inlet opening 6, after which the stopper 8' is applied thereto andcloses effeotively the inlet opening. This powder is discharged from the distributor by an endwise collapsing of the sections 1 and 2 through an axial compression applied thereto. Such movement causes the elastic wall 3 to collapse in a somewhat bellows action and, due to the elasticity thereof as well as the action of the coil spring 13, the end members 1 and 2 are restored to their extended relation. The powder is discharged through the openings 16 from the interior of the container and through the spout 15 upon such collapsing movements.

The distributor is capable of use with any suitable ma terial which is to be dispensed in powder form, such, for example, as insecticides, fungicides, rodent-icides, etc.

The distributor may be handled by the hook or handle 18, and when not in use, may be inverted and hooked over a suitable support, such as a nail, bar, etc.

While the invention has been illustrated and described in one embodiment, it is recognized that variations and changes may be made therein, departing from the invention as set forth in the claims.
